Patent DE-3227221-A1 (DE)
Title: Method of improving the grip of carriageway surfaces
Inventor: SCHNIERING ALFRED DIPL ING
IPC: E01C23/088
Filed: 1982-07-21
Abstract: Improving the grip of polished carriageway surfaces is performed according to the current state of the art by building up the existing wearing course or by material removal. The removal of material takes place by milling, grinding, cutting grooves, scribing, hammering, sand-blasting or flame-blasting. With the exception of sand-blasting, all these methods entail a relatively great loss of substance for the wearing course and correspondingly high expenditure. As has emerged from surprising observations and subsequent investigations, the grip can, however, be improved in the long term just by the mechanical action of a smooth-wheeled roller if, by reducing the contact area, its surface pressure is correspondingly increased. In this case, the protruding constituent parts of the course undergo structural disturbances which are sufficient for a significant improvement in the grip without any appreciable loss of substance occurring. The sub-area treated in this way appears virtually unchanged. However, the microstructure, determinative for grip (with usually adequate peak-to-valley height), is decisively changed. Smooth-wheeled rollers are not suitable for selective improvements of grip, because the customary facings contact the surfaces of old roads only in sub-areas and, with full-area contact, do not produce adequate pressing forces. The method according to the invention utilises the abovementioned surprising finding and is characterised in that relatively narrow rolling bodies having correspondingly hard circumferential surfaces are arranged in groups next to and/or behind one another, travel under high pressures, with or without vibration, over the area to be worked and thereby break up the upper zone of the wearing course material without detaching appreciable amounts of material from the formation. The advantages are a particularly favourable form of grip improvement, low expenditure on energy, high equipment performance, preservation of the wearing course substance and considerable savings in taking up, transporting and dumping removed material.

Patent DE-3233691-A1 (DE)
Title: Resistance welding appliance
Inventor: GOLDGRABE RICHARD
IPC: B23K11/25
Filed: 1982-09-10
Abstract: The resistance welding appliance has an additional unloaded secondary winding (A3-E3) at the welding transformer (T1) and a device which detects the differential voltage between this unloaded winding and the winding electrically loaded during welding. This differential voltage is a measure of the welding current. The duration of the welding operation is influenced as a function of this differential voltage to the effect that the welding time is reduced at high welding currents and increased at low welding currents. In this way, irrespective of interference such as fluctuating mains voltage, variable transition resistance between the parts to be welded, etc., sound welded joints are created, especially when welding on body pins, washers, etc. If the welding current falls below a predetermined minimum value, an alarm (H1) is triggered. As long as a making-current limit (R2) is effective, the alarm is cut off. <IMAGE>

Title: Sports apparatus
Inventor: SCHAWALDER ALBERT C
IPC: A63B69/18
Filed: 1982-10-19
Abstract: The invention relates to a novel training apparatus for skiers which provides the latter with the possibility of practising, at home, the body movements which are necessary when skiing for the so-called swinging or "wedeln" movements. The sports apparatus comprises a tread board which carries, on its underside, rollers which are fastened on the tread board by means of flexible bracing members, for example rubber strands, which, in the rest position, run in the direction of the axis of the rollers. Expediently, in each case a plurality of rollers are held one behind the other in the axial direction by the bracing members. When the person who is training steps onto the tread board and carries out the hip swing which is typical for the swinging movement concerned, the tread board rolls sideways on an arc of a circle, the flexible bracing members being braced. Owing to the flexible property of the bracing members, swinging back from the respective end position in the direction of the opposite end position is facilitated to a considerable extent and learning the posture required for the swinging movement is made simpler.

Title: Method for operating an information transmission system and circuit arrangement for carrying out the method
Inventor: KOEHLER GUENTER DIPL ING
IPC: H04L12/403
Filed: 1983-05-11
Abstract: An information transmission system comprising a central station (1) and at least one substation (2) operates in conjunction with other information transmission systems of the same type on a data bus (3). In this arrangement, the messages transmitted in each information transmission system contain a system-inherent identification code. When identification codes correspond, a mutual influencing of the information transmission systems is possible. To prevent this, each central station (1, 1') sends an operating signal message with system-inherent identification code before a first information message, at least when it is connected to the data bus (3). Another central station (1, 1') having the same identification code and possibly connected to the data bus responds to this operating signal message with a rejection message. Due to this rejection message, the connected central station recognises that another information transmission system is operating with the same identification code on the data bus 3. The identification code can then be changed accordingly. <IMAGE>
Patent DE-3327608-A1 (DE)
Title: Circuit arrangement
IPC: B62D5/07
Filed: 1983-07-30
Abstract: The invention relates to a circuit arrangement for branching a pressure-medium flow arriving at an inlet to a first continuously operating consumer and a second intermittently operating consumer by means of a three-way flow-control valve, the controlled flow being fed to the second consumer as long as there is a demand there. If there is no demand, i.e. when a predetermined pressure, e.g. in a differential lock, is reached, the entire flow is to be fed to the first consumer, e.g. a power-steering mechanism, and in addition the pressure of the second consumer is to be limited. In order to achieve this, the second consumer is protected by a pressure-relief valve downstream of the measuring restrictor of the three-way flow-control valve, and an operating valve is provided which can be switched by an electromagnet against a restoring force from a first operating position into a second operating position, a connection between the second consumer and the outlet being made in the first operating position and a connection to the measuring restrictor being made in the second operating position. Therefore pressure medium is only taken from the first consumer when the electromagnet is excited. When the electromagnet is not excited, the three-way flow-control valve acts like a resistance valve with a low pressure drop.
